Intel Core i5-4570S vs Intel Core i7-2820QM

Core i5-4570S vs Core i7-2820QM comparison

In our benchmarks, the Core i7-2820QM beats the Core i5-4570S in overall performance. Despite this, the Core i5-4570S has the advantage in our gaming benchmark.

When comparing these CPUs we notice that they have the same number of cores but the Core i7-2820QM has more threads. These CPUs have different clock speeds. Indeed, the Core i5-4570S has a slightly higher clock speed compared to the Core i7-2820QM. Also, the Core i5-4570S has a slightly higher turbo speed. The Core i7-2820QM outputs less heat than Core i5-4570S thanks to a significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption.

Most CPUs have more threads than cores. This technology, colloquially called hyperthreading, improves performance by splitting a core into multiple virtual ones. This provides more efficient utilisation of a core. For instance, the Core i5-4570S has the same number of threads as cores. This means the the CPU does not support hyperthreading.
